The atomic displacements in the spherical G–P zones precipitated in an Al–Zn single crystal are studied by analyzing the backscattered energy spectra of high energy protons. The analysis is carried out on the basis of the displaced atom model proposed by Merz and Gerold. The results obtained from the analysis on direct-scattering show that the values of distortion constant are 0.64×10−2 and 1.27×10−2 for the G–P zones with radius 40 Å and 20 Å respectively.
